Define the per-project category and difficulty at the template level,
instead of manually tagging the project pages. While doing this, prefix
the tags with "category:" and "difficulty:" to make them easier to
understand.

The current lpr/lpd system in NetBSD is ancient, and doesn't support modern printer systems very well. Interested parties would do a from scratch rewrite of a new, modular lpr/lpd system that would support both the old lpd protocol and newer, more modern protocols like IPP, and would be able to handle modern printers easily.
This project is not intrinsically difficult, but will involve a rather large chunk of work to complete.
